Read and understand all safety warnings at the beginning
of the manual before beginning installation or any
repair work.
PUMP LOCATION. You probably have spent considerable
time planning where your pump will be located. However,
you may have overlooked some factor that may affect pump
operation or efficiency.
The pump should be located as close to the liquid source
as possible so that the suction line can be short and direct.
It should be located in a clean, open area, where it is easily
accessible for inspection, disassembly and repair. Pumps
installed in dark, dirty areas or in cramped locations are often
neglected, which can result in premature failure of both the
pump and the driver.
The Aurora pump must be installed horizontally. Install
isolating valves on each side of pump so pump maintenance can
be performed without draining the system. Special mounting
requirements may be required if the pump is to be mounted near
a noise or vibration sensitive area.
These pumps are intended for use in applications where the
water supply to the suction connection is permanently flooded.
Operation of these pumps under static suction lift condition is
strictly prohibited.
The installation must be evaluated to ensure that the net
positive suction head available (NPSHA) meets or exceeds the
requirements of NFPA 20.
FOUNDATION. The foundation for your pump must
be sufficiently rigid to absorb any vibration and stress
encountered during pump operation. A raised foundation of
concrete is preferable for most floor mounted pumps. The
raised foundation assures a satisfactory base, protects against
flooding, simplifies moisture drainage, and facilitates keeping
the area clean.
Your pump should be firmly bolted to the foundation, whether
it is a raised concrete base, steelwork wall, or structural
member. The mounting bolts or lag screws should be accurately
located per the applicable Aurora dimension sheet. Refer to
Fig. 1.
LEVELING THE PUMP. Leveling the pump will require
enough shims to support the base plate near the foundation bolts
and at any points of the base plate carrying a substantial weight
load. The shims should be large enough to allow a gap of 3/4"
to 1-1/2" between the base plate and foundation for grouting.

instructions could result in serious personal injury, death or
property damage.

IMPORTANT: The pump base must be set level to avoid
any mechanical difficulties with the pump or motor. The 384
pump was properly aligned, if supplied with a motor, at the
factory. However, since the pump base is flexible, it may
spring and twist during shipment. Do not pipe the pump until
it is realigned. Realign the base after piping is completed and
after the pump is grouted in and bolted down. NOTE: It may
be necessary to readjust the alignment from time to time while
the unit and foundation are new. Realignment will prevent
premature bearing failure, excessive vibration or shaft failure.
Ensure that proper hydronic accessories such as pressure relief
valves, thermal expansion tanks and flow/pressure control
devices are installed in the system. Consult the responsible
party for your system to ensure these devices are installed and
of the proper size.
GROUTING THE INSTALLATION. Grouting the base plate
prevents lateral movement of the base plate and improves
the vibration absorbing characteristics of the foundation by
increasing its mass. A wooden dam should be constructed
around the base plate to contain the grout while it is being
poured. The dam can be built tight against the base plate or
slightly removed from it as desired. Refer to Fig. 2. The entire
base plate should be completely filled with nonshrinkable type
grout. The grout should be puddled frequently to remove any air
bubbles from the grout.
ROTATION. Pump rotation is clockwise when viewed from
the back of the motor. An arrow is also located on the pump to
show the direction of rotation.
INITIAL ALIGNMENT OF THE FLEXIBLE COUPLING.
The pump and driver were accurately aligned at the factory.
However, it is impossible to maintain this alignment during
shipping and handling. Therefore it will be necessary for you
to realign the pump and driver. Flexible couplings are not
universal joints. They should not be used to compensate for
misalignment of the pump and motor shafts. Their function is to
transmit power from the driver to the pump while compensating
for thermal expansion and shaft end movement. The coupling
faces should be far enough apart so that they do not make
contact when the motor shaft is forced to the limit of the bearing
clearance toward the pump shaft.
In order to properly align the coupling, you will need a taper
gauge or set of feeler gauges and a straight edge.
There are two types of misalignment encountered with flexible
couplings: angular misalignment, in which the shafts are not
parallel, and parallel misalignment where the shafts are parallel
but not on the same axis.
To check angular alignment, insert a feeler gauge or taper gauge
at any four places 90-degrees apart around the coupling halves.
Insert shims under the driver feet until the same reading is
obtained at all four check points. The pump and driver will then
be in angular alignment.
To check parallel alignment, a straight edge should be held
against the edges of the coupling halves at any four places 90°
apart around the coupling. The straight edge should be parallel
to the pump and driver shafts at all times. Insert shims until
the straight edge lies flat against both coupling halves at all
four checkpoints. The pump and driver will then be in proper
parallel alignment. Refer to Fig. 3.
For fine alignment, 3500 RPM operation, for all other
coupler types.
A dial indicator should be used when greater alignment
accuracy is required. Use the following alignment tolerances
unless specified otherwise by the coupling manufacturer. On
sleeve type couplings make sure there is at least 1/8" end
clearance between the sleeve and the two coupling halves.
To check angular misalignments, mount the dial indicator
base to the coupling half, and position the dial indicator button
on the front or rear face of the opposite coupling half. Set
the dial to zero, rotate both coupling halves together, making
sure the indicator button always indicates off the same spot.
Misalignment values within 0.004 inches TIR per inch of
coupler radius is permissible.

Warning: Sudden Start-Up Hazard
Disconnect and lock out power source before servicing.
Failure to follow these instructions could result in serious
personal injury, death or property damage.
Warning: Lifting Hazard
The motor and pump assembly may be very heavy. Use
extreme caution and safe lifting equipment during the lifting
procedure. Failure to follow these instructions could result
in serious personal injury, death or property damage.
MODEL 384

To check parallel misalignment, mount the dial indicator base
to one coupling half, or shaft, and position the dial indicator
button on the outside diameter of the opposite coupling half. Set
the dial to zero. Rotate both coupling halves together, making
sure the indicator button always indicates off the same spot.
Misalignment within 0.004 inches TIR is permissible.
Pumps are supplied by the manufacturer with adequate guards
for the coupling. The installer is to ensure that any additional
guarding required shall be compliant with EN 953.
PIPING:
SUCTION PIPING. The suction piping should be short and
direct with as few elbows and fittings as possible to keep head
loss (from friction) at a minimum. A horizontal suction line
should have a gradual rise to the pump, and pass under any
interfering piping. The suction pipe diameter must be at least
the diameter specified by NFPA 20. All joints must be tight to
maintain prime on the pump.
INCREASERS & REDUCERS. For installations where pump
suction flange is smaller than system piping: Eccentric reducers
should be installed directly at the suction nozzle, with the taper
at the bottom to prevent air pockets from forming. Straight
taper reducers should never be used in a horizontal suction line
because of the air pocket that is formed at the leg of the reducer
and the pipe. Refer to Fig. 4.
For installations where pump suction flange is larger than
system piping: Either concentric or eccentric reducers can be
used, and should be installed directly at the suction nozzle.
DISCHARGE PIPING. Discharge piping should also be short
and direct with as few elbows and fittings as possible to keep
head loss (from friction) at a minimum. The discharge pipe
diameter must be at least the diameter specified by NFPA 20.
DISCHARGE VALVES. The discharge piping must include a
check valve and an indicating isolation valve. The check valve
should be located between the isolation valve and the pump.
If an increaser (or reducer) is used in the discharge piping, the
increaser (or reducer) should be installed between the pump
nozzle and the check valve. The check valve protects against a
reverse flow of the liquid if the driver fails. Refer to Fig. 5.
PRESSURE RELIEF VALVE. All End Suction Fire Pump
Models are provided with a pressure relief valve by the pump
manufacturer to prevent an over pressure condition. For
rotodynamic pumps, these valves are to set in the field at a point
between the duty pressure and shut-off pressure to prevent a
no-flow condition. For rotary positive displacement pumps,
the pressure relief valve is factory set to 10% above the duty
pressure and sealed with a safety wire, and are not to be field
adjusted.
SPECIAL CONSIDERATIONS FOR DIESEL ENGINES:
ENGINE FLUIDS. Many diesel engines are shipped dry and
must have lubricating oil and coolant added prior to start-up. It
is the installer’s responsibility to assure that all fluid levels are
correct to avoid damage to the engine.
DIESEL ENGINE WIRING. The End Suction Fire Pump
controller must be wired to the diesel engine’s junction box.
This is usually a simple matter of connecting like-numbered
terminals of each with the correct wire gauge size. Refer to
panel manufacturer’s wiring diagram.
The electric solenoid valve in the diesel engine cooling loop
piping must be wired to the engine junction box. Either red wire
goes to terminal 1; the other red wire goes to terminal 11; the
green wire is grounded to the engine block.
Engines may have 12-volt or 24-volt systems, but all batteries
furnished are 12-volt. Since dual battery sets are required by
N.F.P.A. 20, two batteries are furnished for 12-volt systems and
four batteries are furnished for 24-volt systems.
Aurora’s standard battery racks are designed to keep the
batteries elevated off the floor for housekeeping purposes. They
must be placed on a suitable level surface as close to the diesel
engine as possible. Each rack holds two batteries; one rack is
required for 12-volt systems and two racks for 24-volt systems.
If two racks are used, they are to be placed side-by-side and not
stacked.
Warning: Coupling Failure
Do not operate pump with coupling out of alignment.
Ensure final coupling alignment according to coupling
manufacturer’s instructions. Coupling, pump or driver
failure may occur. Failure to follow these instructions could
result in serious personal injury or death and property
damage.

Electrolyte is not furnished by Aurora Pump; it must be
procured locally (approximately 16 quarts per battery).
Electrolyte must be added and the batteries charged at a low
rate for at least 24 hours prior to start-up. It is recommended
for safety reasons that the batteries be filled with electrolyte
only after being placed in their permanent positions in the pump
room.
The positive battery terminal of each battery (or pair of batteries
for 24-volt systems) is connected to one of the engine’s starter
contactors. The negative terminals are to be connected to the
engine block or other suitable ground. Aurora Pump’s standard
battery cable wire gauge sizes are selected for a maximum
10-foot circuit length (5-foot cables). Longer cables will require
heavier gauge wire to be used.
Power wiring to the engine’s jacket water heater must be
completed only after it has been assured that there is sufficient
coolant in the engine. Most heaters are continuously energized
when wiring is connected and will burn out the heating element
if no water is present. This failure is not covered by warranty.
Refer to engine manufacturer’s data sheet for correct voltage of
the heater.
DIESEL ENGINE COOLING LOOP PIPING. The cooling
loop system diverts a small amount of water from the pump
discharge through the engine’s heat exchanger to help control
the operating temperature of the engine. Prior to start-up, it
is recommended that this piping be checked for damage or
displacement that might have occurred during shipment.
During normal operation, the top two valves of the cooling
loop (in the by-pass line) are to be closed, and the lower two
valves (in the pressure regulated line) are to be open. Failure
to observe this may result in overpressurization of the heat
exchanger when the pump is started, causing damage to the
engine.
Piping from the engine’s heat exchanger to a drain
is to be provided by the installer. It is important to use the
recommended size piping to reduce back pressure and avoid
overpressurizing the heat exchanger.
Danger: Can Cause Blindness
or Severe Burns
Batteries contain sulphuric acid electrolyte. This is a highly
CORROSIVE POISON. They also produce a mixture
of hydrogen and oxygen gasses which will EXPLODE if
ignited.
WHEN WORKING ON OR NEAR BATTERIES,
MIXING OR POURING ACID SOLUTIONS,
ALWAYS WEAR PROTECTIVE CLOTHING AND
PROTECT EYES WITH SAFETY GOGGLES. KEEP
SPARKS, FLAMES AND CIGARETTES AWAY.
KEEP BATTERIES AND ACID OUT OF THE REACH
OF CHILDREN.
If acid contacts skin or eyes, flush affected parts with clean
water immediately and repeat for 15 minutes. Then seek
prompt medical attention.
If acid is taken internally, call medical help immediately.
Drink large quantities of water, milk or milk of magnesia,
beaten eggs or vegetable oil.
Acid spilled on clothing, workbench or floor may be
neutralized with baking soda or ammonia solutions, in
metallic containers.
Use only glass, ceramic or acid resisting plastic vessels.
Never discard used containers before they have been rinsed
clean, then puncture them to prevent further use.
When charging batteries, keep area well ventilated and
bar general access. Connect/disconnect batteries only
when charge is switched off. Make sure tools cannot short
circuit battery terminals. Keep vent caps on battery during
charging.

A length of PVC tubing is provided by Aurora to be connected
to the petcock in the cooling loop piping in order to vent the
system and visually verify the flow of water through the heat
exchanger.
DIESEL ENGINE FUEL SYSTEM. The fuel tank should be
installed so that the supply outlet is at the same elevation as the
engine’s fuel pump. Since the unit base is usually elevated as
described earlier, this may require that the fuel tank is likewise
elevated. The means of elevating the tank is the responsibility
of the installer. Substituting the legs furnished with the tank
with pipes of greater length is not a recommended method of
elevating the tank.
All fuel fittings shown in Figure 9 are shipped loose for field
installation. They are to be assembled as shown in Figure 9
to be consistent with Figure A-8-4.6 of N.F.P.A. Pamphlet
20. Installation may vary at the discretion of the installer with
the approval of the local authority having jurisdiction. Note
that some sections of common piping needed to complete this
installation are not furnished by Aurora and must be procured
locally.
Tube fittings are provided to allow the use of 5/8" O.D. tubing
for the fuel supply and return lines (the tubing itself is NOT
furnished by Aurora). If hard piping is used, these tube fittings
are simply to be discarded.
Diesel fuel is not furnished by Aurora and must be procured
locally prior to start-up.
DIESEL MUFFLER AND EXHAUST SYSTEM. A
commercial grade muffler and flexible connector are furnished
as standard on diesel End Suction Fire Pumps. If necessary,
additional fittings needed for connecting these to the engine are
also provided.
Commercial grade mufflers have NPT connections on 3" and
3-1/2" sizes, slip-on (automotive type) connectors for 4", 5" and
6" sizes, and 125# ANSI flanged connections for larger sizes.
Optional residential grade mufflers have NPT connections on 3"
and 3-1/2" sizes; ANSI 125# flanges on 4" and larger sizes.
Piping, elbows and other components required to route
the exhaust to the outside are not provided by Aurora. It is
suggested that the building contractor or on-site engineers
design and install the remainder of the exhaust system.
Mufflers are sized by Aurora to allow the engine to operate
at its rated speed with nominal back pressure. However, if
more than 25 feet of additional piping and/or more than four
90-degree elbows are required to complete the system, it is
important to contact the factory for re-evaluation of the system
with respect to back pressure. A larger muffler and piping may
be required to allow the engine to operate properly.
The flexible connectors furnished by Aurora are intended for
use as a vibration control device and cannot be substituted for
elbows in the piping system. It is recommended that the flexible
connector be placed as close to the engine’s exhaust outlet as
possible. The muffler and piping must be supported to prevent
strain on any diesel engine component.
START-UP AND FIELD ACCEPTANCE TEST:
GENERAL. The following is a general outline for starting and
field testing End Suction Fire Pump systems. It is recognized
that requirements and methods may vary depending on local
customs and practices. Those involved in End Suction Fire
Pump sales MUST fully understand all local requirements and
N.F.P.A. Pamphlet 20. A general method to follow is outlined
below.
Be specific and complete when ordering End Suction Fire
Pumps and accessories so that all necessary and correct items
are on hand for the start-up. Trouble cannot be tolerated on the
day of the field acceptance test.
Visit the jobsite after delivery of the equipment to verify that all
components ordered have been received and are correct for the
installation.
Visit the jobsite again after installation to assure that the
components have been correctly assembled and installed.
After the installation is complete and the End Suction Fire
Pump system is pressurized and checked by the contractor, the
following items must be verified:
1. Coupling has been properly aligned.
2. Motor has been “bumped” to check for proper rotation.
3. Diesel engine (where applicable) has been properly
serviced, necessary fluids added, batteries filled and
charged, jacket water heater operating.
INITIAL TEST. The following steps are basic for an initial test
of the End Suction Fire Pump system:
1. Close the valves on all discharge outlets.
2. Open the suction valve.
3. Having read the controller manual and gained an
understanding of its operation, set the End Suction Fire
Pump controller to “manual”. The Jockey pump panel
should be set to the “off’ position.
4. With the controller door closed, start the End Suction
Fire Pump.
5. Adjust the packing to allow approximately 60 drops per
minute to flow from each packing box. Further adjustment
may be required later, so a recheck upon completion of the
test is advised.

6. Close the relief valve completely for a brief period to verify
that the shut-off pressure agrees with that on the certified
factory test curve.
7. Adjust the casing relief valve (electric-driven units only) to
allow enough flow to keep the pump cool.
8. Stop the End Suction Fire Pump.
9. Set the End Suction Fire Pump controller to the “automatic”
position.
10. Slowly lower the system pressure with the control valve.
The End Suction Fire Pump should start. Observe this
starting pressure and adjust if necessary. (Adjustment
procedure varies with controller manufacturer.) Stop the
End Suction Fire Pump.
FIELD ACCEPTANCE TEST. Personnel on hand for the End
Suction Fire Pump field acceptance test should include the
controller representative, diesel engine service technician (if
applicable), representatives of the insuring agency and local fire
authority, as well as those responsible for building maintenance
and supervision.
Equipment needed for the field acceptance test includes:
1. Calibrated ammeter.
2. Volt meter.
3. Tachometer.
4. Pitot tube & gauge.
5. Calibrated suction and discharge gauges with 1/4%
accuracy. (Gauges furnished with the pump are 2%-3%
accurate and could be troublesome for the field acceptance
test.)
6. 50 feet of 2-1/2" hose for each connection on the hose
manifold.
7. Play pipe with suitable nozzle for each hose.
While field acceptance tests vary by location, the following
steps are usually taken. Additional operations may be required
depending on the special needs in some territories.
1. A hose and play pipe are connected to each valve on the
hose manifold.
2. The discharge valve leading to the building’s fire system is
closed.
3. The discharge valve leading to the hose manifold (or “test
header”) is opened.
4. The suction valve is opened.
5. All relief valves are closed.
6. One hose valve on the hose manifold is opened.
7. With the End Suction Fire Pump operating, the hose valve is
adjusted for a flow of 500 GPM at the play pipe as indicated
by the pitot tube. Refer to Table 1 to determine the pressure
vs. flow for the size play pipe used for this test.

8. By opening additional valves and measuring the flow equal
to 500 GPM, readings of 1000 GPM, 1500 GPM, 2000
GPM, etc. can be determined.
9. Open the necessary hose valves to obtain the total rated
flow. When this flow is assured, check and record the
following data:
a. Suction gauge pressure
b. Discharge gauge pressure
c. RPM with tachometer
d. Voltage
e. Amps (on all legs)
10. Verify that the flow remained constant during the above
data readings.
11. Adjust hose valves to achieve 150% of rated flow. Proceed
as before and record the necessary data.
12. Repeat these steps as required by supervising authorities to
obtain the desired number of points on the test curve.
13. Finally, close all valves and record the above readings in
Step 9 at shut-off (zero GPM) condition.
If a number of automatic and/or manual starts are to be
demonstrated, this series of tests can now be conducted.
The Jockey Pump controller must be set to start the Jockey
Pump at a pressure greater than that of the main End Suction
Fire Pump. The following procedure may be used to accomplish
this.
1. The main End Suction Fire Pump controller is set to the
“off’ position.
2. The Jockey Pump controller is set to the “automatic”
position.
3. The system pressure is slowly reduced by opening the test
valve until the Jockey Pump starts. Observe the pressure at
which the Jockey Pump starts.
4. Allow the Jockey Pump to continue running until the system
pressure rises enough to stop the pump automatically.
Typically, there is a minimum of 10 psi between the “pump
start” and “pump stop” pressure readings.
5. Adjust the set points in the Jockey Pump controller as
necessary to achieve the desired results. As with the main
End Suction Fire Pump controller, adjustment methods vary
with controller manufacturer.
IMPORTANT:
Upon successful completion of the field acceptance test, the
following points must be verified:
1. The discharge valve leading to the outside hose manifold
should be closed.
2. The discharge valve leading to the building fire protection
system should be opened.
3. The casing relief valve should be set to a pressure just
below the shut-off pressure of the pump.
4. The main relief valve (if applicable) should be set to a
pressure just above the maximum system pressure.
5. Both the End Suction Fire Pump and Jockey Pump
controllers should be set to the “automatic” position.
6. Any alarm systems disabled during the tests should be
reactivated.
7. The individual or authority responsible for maintaining the
building’s fire protection system must be made aware of all
settings and the operational condition of the system before
leaving the site.
MAINTENANCE:
Your Aurora pump requires no maintenance other than periodic
inspection, occasional cleaning and lubrication of bearings. The
intent of inspection is to prevent breakdown, thus obtaining
optimum service life. The liquid end of the pump is lubricated
by the fluid being pumped and therefore does not require
periodic lubrication.
Table 1. GPM At Various Nozzle Sizes.
MODEL 384
10
LUBRICATION OF IMPELLER SHAFT BEARINGS:
Regreaseable bearings will require periodic lubrication and can
be accomplished by using the zerk or lubrication fittings in the
cartridge cap and power frame. Lubricate the bearings at regular
intervals using a grease of high quality. Mixing of different
brands of grease should be avoided due to possible chemical
reactions between the brands which could damage the bearings.
Accordingly, avoid grease of vegetable or animal base which
can develop acids, as well as grease containing rosin, graphite,
talc and other impurities. Under no circumstances should used
grease be reused.
Overlubrication should be avoided as it may result in
overheating and possible bearing failure. Under normal
application, adequate lubrication is assured if the amount of
grease is maintained at 1/3 to 1/2 the capacity of the bearing
and space surrounding it.
In dry locations, each bearing will need lubrication at least
every 4,000 hours of running time or every 6 to 12 months,
whichever is more frequent. In wet locations (exposed to
dripping water, to the weather, or to heavy condensation such
as is found in unheated and poorly ventilated underground
locations) the bearings should be lubricated at least after every
2,000 hours of running time or every 4 to 6 months, whichever
is more frequent.
Use Chevron SRI, NLGI2.
Lubricate motor per motor manufacturer’s instructions.
GENERAL INSTRUCTIONS:
1. Keep this pump and motor properly lubricated.
2. Inspect the pump regularly for leaky seals of gaskets
and loose or damaged components. Replace or repair
as required.
ELECTRICAL WIRING. Normally, your pump will be
supplied with an attached drive motor. The motor should be
wired in accordance with the wiring diagram found on the
motor nameplate. Be sure the voltage, frequency, and phase of
your power supply corresponds with the nameplate data. It is
advisable to provide a separate switch and overload protection
for your pump motor to protect against power failure in some
other area. Conversely, if the pump motor develops electrical
problems, it will be isolated from other equipment.
PRESTARTING INSTRUCTION. The coupling halves
should be connected. Prior to connection, however, the drive
motor should be started to make sure the direction of rotation
is the same as the direction indicated by the arrow on the
pump casing.
When the pump is used in conjunction with electric motors
and controls, these components must be in accordance with
EN 60529 IP 22. Electrical equipment applied is to conform
to the requirements of EN 50081 parts I or 2, and to EN
50082 parts 1 or 2, and the relevant parts of EN 6100 with
regard to electromagnetic compatibility. Protection of the
electrical assembly against electrostatic phenomena shall be
per paragraph 5.2.2.2 of EN 809. General compliance of the
electrical assembly shall be per EN 60204-1. The installer shall
ensure that any displays and control actuators are designed and
installed in accordance with EN 894. The nature of the pumped
liquid precludes the need for an emergency stop device; the
pump can be shut down by normal means. Any electrical
equipment shall be properly earthed.
Overall assembly shall be shown to comply with 98/37/EC
Annex 1 paragraph 1.7.4 (f) by the final assembler with respect
to noise and vibration.
Installation must comply with the Machinery Directive 98/37/
EC as well as any other applicable national regulations in the
member state of the installation. The final installation must not
be put into service until it has been declared in conformity with
the provisions of the Machinery Directive.
PUMP DISASSEMBLY: For frame mounted pumps, model
384.
Any disassembly/assembly procedures performed will
require testing per NFPA 20 Table 14.5.2.3 after
re-assembly has been completed prior to the pump being
returned to service.
Read and understand all safety warnings at the beginning
of the manual before beginning installation or any
repair work.
1. Ensure the electrical power is locked out, the system
pressure has been lowered to 0 psi and temperature of the
unit is at a safe level before beginning any disassembly of
the pump.
2. Isolate the pump from the system by closing the valves that
should be located on both the suction and discharge of the
pump. Loosen the drain plug at the bottom of the casing and
drain the pump. The flush line assembly (optional 1, 3, 2
and 75) should be removed at this time.
Inspect removed parts at disassembly to determine if they can
be reused. Ball bearings that turn roughly or show wear should
be replaced. Cracked castings should never be reused. Scored
or worn pump shafts should be replaced. Gaskets should be
replaced at reassembly simply as a matter of economy. They are
much less expensive to replace routinely than to replace singly
as the need arises.

lines from the pump including compression connections
(1 and 2) and tubing (3).
16. Reinstall the coupling guard.
17. Open isolation valves and inspect pump for leaks.
18. Return pump to service.
STARTING PUMP AFTER REASSEMBLY:
Do not start pump until all air and vapor has been bled and
until making sure that there is liquid in the pump to provide the
necessary lubrication for the packing.
When the pump is returned to service, additional care must
be given to packing box to ensure a proper packing life. It is
necessary to allow 60–120 drops leakage per minute through
the packing for lubrication purposes. If the flow rate is other
than this, the capscrews should be either loosened or tightened
one quarter turn at a time to acquire the correct leakage (both
capscrews must be turned equally to prevent cocking of the
gland). It will take approximately ten minutes at any one gland
setting before the leakage rate will stabilize. When in doubt,
choose the greater leakage rate since overly tight packing will
ruin not only the packing, but the sleeve as well.
POWER FRAME OR PUMP SHAFT
DISASSEMBLY/REPLACEMENT:
